Betasso Presserve. Close by, very smooth winding trail in the foothills behind Boulder. This extremely popular trail is so popular that it is off limits on Wednesday and Saturdays, also some of the trails are one-way trails.

Where: Betasso Preserve is located 6 miles west of Boulder off Sugarloaf Road. Basically look for a right turn onto a paved road about half a mile after you pass through the one and only tunnel on Boulder Canyon.

Big plains loop that is anything but flat. Enjoy the rolling hills of the southern plains and take in the beautiful vistas that lays out throughout the course. Mostly pleasant ride with just a few sections that are extra technical where some beginners might dismount. The length will get you more than the technical sections will.

Simple, close and short are what make NCAR a classic hill climb choice in Boulder. Maybe you only have 30 minutes to ride or maybe you were not gifted with the body of a hill climber, whatever the reason NCAR Hill Climb is a nice ride for all types of cyclists.

Lee Hill Road via Left Hand Canyon
Head north out of Boulder. Turn left up Left Hand Canyon. At the split, approximately 5 miles up the canyon, head towards Ward. In another mile turn left up Lee Hill. If when you get to the bottom of Lee Hill and you still have time take a right up Wagon Wheel Gap and explore Bow Mountain.

Peak to Peak Highway Not a ride for beginners but not because this ride is hard but just hard to get to. This route travels south from Estes Park all the way down Hwy 6 to near Black Hawk. There are many ways to access this beautiful route, most common is either via Hwy 7 in Lyons or from Ward. Ward is the high point on this route so once you are there everything is nearly downhill! Suggested route is up Hwy 7 from Lyons then down Left Hand Canyon.

You've seen the route on the movie American Flyers you've read about it in countless cycling history books now experience the ride your self! While the ride isn't quite as moon-scaped as in the old days due to the development of many of the surrounding areas the road is still the same. Lots of rollers with great views of the foothills. This course has probably more history than any in Colorado having been apart of the Red Zinger Classic and the Coor Classic races back in the 70's and 80's.

We have talked about it a lot on 303Cycling. It lies just north of the city limits of Boulder. Its 75% dirt, very little traffic and rolling terrain. I often try to incorporate a part of this loop into my rides. Check out the classic! Find out more about the History of the Boulder Roubaix

Prairie Vista - Springbrook LoopDifficulty: ModerateDescription: Located just south of Boulder this is a great mountain bike ride. Little of everything for this ride (i.e. smooth, rocks, up and downs). Lots of options to make the ride longer.

Foothil/Eagle/Sage Loop TrailDescriptionLocated in the rolling hills near the Boulder Reservoir this trail is popular for hikers, runners and casual cyclist. While the most of the trail is smooth enough for a cross bike it is strongly considered that you use a mountain bike.

The Switzerland Trail is an the reminets of a old railroad that provided supplies to Boulder mining towns and provided others with quick tourist access to the mountains. All that is left of the 12.5 mile route is a road bed that gradually rises and falls as it winds its way North/South from Sugarloaf to Ward...more details
